Whispernet

Amazon has an agreement with Sprint so that the Kindle may use a Sprint cell tower free of charge for the Kindle owner. Within the U.S. use of Whispernet (Kindle accessing Sprint) is free. Webbrowsing is free, receiving of books and SINGLE-issue magazines are free.

Whispernet makes use of the high-speed network established by the wireless cell phone provider Sprint. This network, in turn, uses EVDO technology, which is faster than other mobile wireless networks.

When you activate a menu (by pressing the Menu button), your wireless status is indicated by a 1X or 3G icon that appears to the left of the wireless coverage bars on the top line of the Kindle screen. The Kindle uses the 3G network when it’s available; otherwise it uses the slower 1X RTT network.

Web and Internet

The Kindle isn’t a fully-functional Web browser, but it lets you browse Wikipedia and other text-oriented Web sites, where you can check your e-mail and perform other common functions. The Kindle gives you free wireless access to the Web. And you don’t have to pay a monthly fee to use your Kindle to go online.
